I wish I could remember, or find the JBS issue or PR with the discussion, to remind us as to why the implementations were put into a separate module in the first place.

The changes in the PR looks okay. I'm just wondering if we also need to re-examine the wording in RandomGeneratorFactory methods where it documents  "uses the service provider API". I'm surprised this is documented as an implementation requirement. Also "service provider API" should really be ServiceLoader API.

One other thing is that we'll need a release note for this change. It's possible there are scripts somewhere in the wild that use jlink and specify the jdk.random module in the sets of modules to include. These scrips will break with this change. I don't think it's worth leaving a hollowed out module in its place but we should at least document that it has been removed.
